INSULATOR.

Application filed February 24, 1923. Serial No. 620,997.

To @ZZ whom t may concern:

Be it known that I, LEON H. BEAN, a citin Zen of the United States,residing at .Paw-

tucket, in the county of Providence and State of Rhode Island, haveinvented new and useful Improvements in Insulators, of which thefollowing is a specification.

This invention relates to insulators. Some of the objects of the presentinvention are: to produce an insulator which is comparativelysimple andpractical and especially adapted for use in connection with wirelessaerials; to produce an insulator comprising an element which embodiesconnectors and a housing which surrounds said connectors to protect thelatter from the elements of weather such as rain, ice, and snow; toproduce an insulator element having a connector at each end thereofbetween which is formed a chamber which may contain oil in which theopposed ends of the connectors terminate, the oil acting to prevent highfrequency currents from jumping from one connector to another; to employin conjunction with an insulator element, a housing having corrugatedend portions each of which has an opening therein, the corrugationsserving to thwart the effect of moisture and the openings serving topermit accesi to the connectors of said e ement;

and with these and other objects in view the invention resides in theparticular provision and relative disposition of the parts hereinafterfully described and illustrated in the accompanj-/ing drawing, in which:

Figure 1 is a view illustrating the frame or the type of insulator ofthe present invention being' shown in section longitudinallytherethrough.

Figure 2 a perspective view of the connector element.

Figure 3 is a transwrsc sectional view tal-:en on line 3-8, Figure 1.

Referring now more particularly to the several views of the drawing, forall of the details of the present invention, it will be apparent thatthe same includes a connector element l0 having housing portions 11. Theconnector element 10 in reality a shell 12 of suitable material withheads 13 of insulating material screw-threaded in said shell andconnectors 11 which may be made of any desired material. Each head 13has attached thereto a connector 14 in any preferred manner. Eachconnector is formed with an eye 15. One head 13 and its connector 14 iscarried at each end of the shell 12. The heads 13 and the wall of theshell 12 form a chamber 1G whichis filled with oil 17. The connectorelement 10 when employed for supporting a wireless aerial has one end ofthe aerial connected to one connector 14E and the other connector 14 hasconnected thereto the anchor of a mast. The housing portions 11 at theopposite ends of the shell 12 are corrugated or screwthreaded as at 18and each end has an opening 19 therein. The corrugation or screwthreads18 serve to thwart the capillary action of moisture which mightotherwise collect above the connectors 141 and serve for theattachmentof the heads 13, whereas, the openings 19, give access to the connectorsfor permitting the attachment and removal of the endsl of the wire.;which are adapted to be connected therewith. It should now be manifestthat by virtue of the intervention of the oil filled chamber 16 theopposing ends of the connectors 14 terminate in dead ends and allows theuse of high frequency waves when broadcasting. If desired the chamber 16may merely contain air.

What is claimed as new is 1. An insulator comprising a shell, having itsends internally screw-threaded, spaced heads of insulating materialrespectively threaded into said ends, the space between said headsdefining a chamber, a connector' carried by each head and extending onopposite sides thereof, each connector having an eye extendingexteriorly from the heads, said shell having interiorly corrugated endwalls.

2. An insulator comprising a shell having its ends internally screwthreaded, a head of insulating material adjacent each end of said shelland co-acting with the threads of the respective ends, a connectorremovably carried by each of the heads and each connector having an eye,and a slot formed in said shell at opposite ends thereof.

An insulator,comprising a shell having spaced heads of insulatingmaterial detining a chamber for the reception of oil, and connectorscarried by said heads and each having one end extending into saidchamber, substantially as and for the purpose specilied.

In testimony whereof I have afxed my signature.

LEON Il. BEAN.
